What is a climax community

A climax community is a stable community of a diverse number of species. The repetitive replacements of serial community's eventually leads to a establishment known as a climax community. An example can be Australia, because it is a climax forest ecosystem

Its a community in its final stage of sucession

What is the product of transcription and translation

proteins

How does translation form proteins

Peptide bonds connect amino acids. ~

What describes a DNA mutation

changes in the DNA sequence

How are mutations prevented during DNA replication

DNA polymerase checks DNA for errors.
DNA polymerase checks DNA for errors by breaking the hydrogen bonds between the paired nitrogen bases in the DNA molecule. This causes the molecule to separate into two individual strands.

Which of the following determines the specificity of a DNA probe

Base

What correctly compares the oxygen isotopes 16O and 18O

16O has 8 neutrons, whereas 18O has 10 neutrons.

Which type of mutation results in the formation of a protein with one incorrect amino acid-

Missense is a type of mutation which results in the formation of a protein with one incorrect amino acid.

Why does a detetion mutation usually cause more defect during protein synthesis than point mutation

Mutation usually causes the entire base sequence to defect. This usually happens during the protein synthesis.

Ice floats on water because ice is less dence than water how helpful to fish that live in a lake

The ice that covers a lake actually insulates the deeper water preventing it from freezing too, this allows fish to continue to swim and feed during the winter.

Which of these is a result of increased biodiversity in an ecosystem

Answer this question…

Increased ecosystem stability

Two atoms are isotopes of the same element. Which of the following should be different for these two atoms

Answer this question… The number of neutrons

In an experiment a scientist makes a radioactively labeled probe using human DNA she then discovers that the probe hybridizes to a small segment of DNA isolated from plant what can she conclude from h

The plant might have a gene that is similar to a human gene

-Apex

What is a following reactions that is used to radioactively label DNA

Synthesis of new DNA
